(6) Lower vehicle.
(7) Start the engine and inspect for exhaust leaks.
Repair exhaust leaks as necessary.
(8) Check the exhaust system for contact with the
body panels. Make the necessary ajustments, if
needed.
HEAT SHIELDS
DESCRIPTION
The catalytic converters have an integral heat
shield attached to them and are not to be removed.

OPERATION

Heat shields are needed to protect both the car and
the environment from the high temperatures devel-
oped in the vicinity of the catalytic converters.
CAUTION: Avoid application of rust prevention com-
pounds or undercoating materials to exhaust sys-
tem heat shields on cars if equipped. Light over
spray near the edges is permitted. Application of
coating will greatly reduce the efficiency of the heat
shields resulting in excessive floor pan tempera-
tures and objectionable fumes.
